Question

PLEASE HELP: Solve for x. 3(x-1) - 4x greater than or equal to -3

Answer 1

Our inequality is 3(x-1) - 4x ≥-3. We can solve this like we solve for x in a regular equation. If I multiply 3(x-1), our new inequality is 3x -3 - 4x ≥ -3. If we add 3 to both sides and subtract 4x from 3x we have -x ≥ 0. But we want the value of x to be positive,  not negative. So we multiply both sides by -1 and change the sign from greater than to less than. We get x ≤ 0.
